Steps to Calculate GCD of 73, 17, 85, 65 using LCM Formula

Given numbers are 73, 17, 85, 65

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(73, 17) = 1241

GCD(73, 17) = ( 73 x 17 ) / 1241

= 73 / 17

= 73


Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1


Step3:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1


So, Greatest Common Divisor of 73, 17, 85, 65 is 1
